The widespread use of computerized >databases requires consistent and "correct" use of terms--this document >provides fills this need. The major sections of the document address >Site Description, Soil Profile Description, Geomorphology, Geology, Soil >Taxonomy. Anyone interested in properly describing soils needs to >consult this source. Although primarily written for the college level, >the diagrams and descriptions could benefit anyone. > >http://www.statlab.iastate.edu/soils/nssc/field_gd/field_gd.htm > >"Experts Pick: Top 10 Space Science Photos" was a recent article at the >"space.com" web site that uses "two veteran image pickers to choose the >pictures they think represent the best, most intriguing, most >scientifically important space science images ever to come from their >respective domains." Images include "Pillars of Creation," "Earthrise >over the Moon," "Volcanoes on Io," and more. > >http://www.space.com/scienceastronomy/astronomy/top10_images_010925-1.html > >"Evolution-Deep Time" from PBS uses Flash animations in a timeline bar >to summarize significant events in geologic history.
